Sharjah24 – Reuters: Blocks of molten lava as large as three-storey buildings rolled down a hillside on the Spanish island of La Palma while a series of tremors shook the ground on Sunday three weeks after the volcanic eruption.

There were 21 seismic movements on Sunday, with the largest measuring 3.8, the Spanish National Geological Institute (ING) said, shaking the ground in the villages of Mazo, Fuencaliente and El Paso.

The blocks of red-hot magma flowed down the side of the Cumbre Vieja volcano were the size of three-storey buildings, the Spanish Institute of Geology and Mining said on Sunday.

The lava flow, with temperatures of up to 1,240 degrees Celsius (2,264 degrees Fahrenheit), destroyed the last few buildings that remained standing in the village of Todoque, the Canary Islands Volcanology Institute said on Twitter.

There was a partial cone collapse near the volcano's emission vent on Saturday, Stavros Meletlidis, a spokesman for ING said.

Rivers of lava have destroyed 1,186 buildings since the eruption on Sept. 19, the Canary Islands Volcanic Institute said.
